To help you think of ideas, it can be useful to look around in your local area at groups of people that might be interesting to study. Whether your paper is based on people of different ages, different ethnic groups, or any other shared characteristics, using a local group can be easier when it comes to researching for your paper.
It may be that you want your ethnographic essay to be based on people of interest in the way that they have helped others. A good way of thinking of topics is to think of inspirational people that have helped you during your life, or helped others.
For example, you may wish to look at the nurses in a particular area or volunteers, or any other groups of people that do inspiring things. It could even be that you look at groups of people that have overcome adversity in their life, such as people who have suffered serious illnesses.
If you’re still unsure of what ideas to use for your paper, then a good solution is to look at prewritten papers. It could be that you source past papers that have been written by students from your university or college, or you could even look for free papers that are widely available online. Of course, if you choose to use topic ideas from old papers, it is important that you take care to make the title is unique as possible, so as not to put yourself at risk of plagiarism.
Whilst looking at old papers that other people have written, so as to help think of topic ideas for yourself, you can even get an idea of what research methods you can use and a wide variety of other information.
